That's right, teeth whitening. I'm not even making this up. The system involves the usual peroxide strips, as found in other whitening treatments, as well a mouthpiece. The theory is that the sound "energy" works in the same way that current light-based whitening systems do, and "stimulates the peroxide" to make your teeth whiter. And what about the music? Well as it turns out, the sound will also be conducted through your jaw to your ears, allowing you to hear the music. Or you can just, you know, use the headphones.

So does it work? The jury is still out on that one. And even if it doesn't whiten, the system will apparently make you look like an idiot, since you'll have a wire coming out of your mouthguard. The kit is selling for $50, so if you're looking for a way to mess with your friends, or are really opposed to Crest Whitestrips, "Rock My Teeth" is almost worth checking out. Almost. If you do buy one, I'd love to know if this actually works or not. I also can't wait for an even more ridiculous accessory to top this one.
